Fauna Of The Isles Of Scilly
The Isles of Scilly are an archipelago off Land's End, Cornwall. Little of the fauna on, above or in the seas surrounding the isles was described prior to the 19th century, when birds and fish started to be described. Most records of other animals date from the 20th century onwards. Historical overview There are few pre-19th-century records for animals. William Borlase published ''The Natural History of Cornwall'' in 1758, commenting on the number of rabbits, and Jonathan Couch's ''A Cornish Fauna'' gave an account of some the animals known in Cornwall and the Isles of Scilly. In the 19th century, following the fashion of the time, birds were shot and stuffed, especially by Augustus Smith and his predecessors on Tresco. Egg collecting was allowed and in the Natural History Museum there are, in the collection, forty-five eggs taken between 1880 and 1936 from Annett, even though it was a bird sanctuary.Robinson, P.

Isles Of Scilly
The Isles of Scilly (; kw, Syllan, ', or ) is an archipelago off the southwestern tip of Cornwall, England. One of the islands, St Agnes, is the most southerly point in Britain, being over further south than the most southerly point of the British mainland at Lizard Point. The total population of the islands at the 2011 United Kingdom census was 2,203. Scilly forms part of the ceremonial county of Cornwall, and some services are combined with those of Cornwall. However, since 1890, the islands have had a separate local authority. Since the passing of the Isles of Scilly Order 1930, this authority has had the status of a county council and today is known as the Council of the Isles of Scilly. The adjective "Scillonian" is sometimes used for people or things related to the archipelago. The Duchy of Cornwall owns most of the freehold land on the islands. Tourism is a major part of the local economy, along with agriculture—particularly the production of cut flowers. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kontikia Andersoni
''Kontikia'' is a genus of land planarians native from islands in the Indo-Pacific region, but several species have been introduced elsewhere. Description The genus ''Kontikia'' includes planarians of elongate body, with a creeping sole that occupies one to two thirds of the body width. The mesenchymal musculature includes well-developed longitudinal muscles forming a ring zone around the intestine. The copulatory apparatus may or may not have a distinct penis papilla, depending on the degree of contraction of the reproductive structures. This led to an initial classification of specimens without a distinct penis papilla in another genus, ''Parakontikia''. Genetics The complete mitochondrial genome of '' Kontikia ventrolineata'' (= ''Parakontikia ventrolineata'') was described in 2020. It displays common unusual characteristics shared with ''Platydemus manokwari'', such as its colinearity, an overlap between '' ND4L'' and '' ND4'' genes and an unusually long ''cox2 ...

Migrant Hawker
The migrant hawker (''Aeshna mixta'') is one of the smaller species of hawker dragonflies. It can be found away from water but for breeding it prefers still or slow-flowing water and can tolerate brackish sites. The flight period is from July to the end of October. ''A. mixta'' occurs in North Africa, southern and central Europe to the Baltic region. Identification ''A. mixta'' is a small ''aeshna'' which appears dark in flight. It is similar in appearance to other aeshnas but has a characteristic "golf-tee" shaped mark on the second segment of the abdomen (S2) which is diagnostic. In flight it looks like a small Emperor dragonfly with a blue abdomen which, when seen from the side, curves down. The main identification problem in the field is distinguishing this species from '' A. affinis'' where the two species fly together. The markings on the side of the thorax are different in '' A. affinis'' and ''A. mixta''. In '' A. affinis'' the sides of the thorax are greeny yellow with ...

Ovipositor
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Enallagma Cyathigerum
''Enallagma cyathigerum'' (common blue damselfly, common bluet, or northern bluet) is a species found mainly between latitudes 40°N and 72°N; It is widely distributed in the Palearctic, and the Nearctic species '' Enallagma annexum'' was at one time considered to be synonymous with it. The species can reach a length of 32 to 35 mm (1.3 to 1.4 in). It is common in many different countries including Russia, Sweden, Norway, Finland, the United States of America, and South Korea. Damselflies are an important link between the health of the aquatic ecosystem and its response to climate change. Habitat These damselflies inhabit freshwater bodies whose conditions range, they have been seen in acidic fens as well as eutrophic ponds. They have been considered one of the more sensitive insects in an aquatic setting. They are important within the trophic levels as they are an intermediate predator. They consume smaller larvae and they are preyed on by fish and larvae bigger than them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leiobunum Rotundum
''Leiobunum rotundum'' is a species of Opiliones, harvestman that is found within the western portion of the Old World. Description ''Leiobunum rotundum'' is chestnut-brown, with a small, smooth, and very long round or oval body and thin black legs, as well as having no separation between the head and the abdomen. The harvestman's legs can be Autotomy, self-amputated if it is in danger of predation, but they do not Regeneration (biology), regenerate. Although the harvestman has no fangs, poison glands, or silk glands, it can protect itself with the scent glands on the front of its body. The scent glands produce a secretion that repels predators. The species has three different types of nephrocytes. Numerous large nephrocytes occur in clusters between the muscles in the anterior region of the body. Smaller nephrocytes are scattered throughout the body, often stuck to tracheoles. The third type of nephrocyte is attached to the heart wall by connective ligaments. The Morphology (bio ...
